We have two glasses that we use to test our multiplayer game. The older one got glitchy. Everything including UIs gets deformed for like a half second, which happens once every 3-4 seconds. While it doesn't affect the gameplay or development, I just want to report it to see if it happened to anybody else.
The A3 is a Lenovo product, if there are warranty issues then it is recommended to report them to Lenovo.
